Up until the fifth edition of the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders, or DSM-5, OCD was considered an anxiety disorder, grouped in the same category as phobias, generalized anxiety disorder, post-traumatic stress disorder, panic disorder, and social anxiety. In DSM-5, however, it has been removed from the group of anxiety disorders and placed in its own category, along with these other related disorders:
- Body dysmorphia, whereby someone has an unrealistic view of a body part (thinking, for example, that his or her nose is immense and repeatedly having plastic surgery).
- Hoarding disorder, in which a person collects an immense amount of items, such as newspapers, and has difficulty throwing them away.
- Excoriation (skin-picking) disorder, in which a person repeatedly picks at his or her skin, such as nails, and can’t resist this behavior even when it results in bleeding.
- Trichotillomania, in which a person can’t resist pulling his or her hair, which can result in bald patches.
